“…Different from the K, Ca has more difficulties to be mineralized by the fact that it makes part of the middle lamella of the cell wall constituents, forming one of the most recalcitrant components of plant tissues, and cofactor of some enzymes involved in the hydrolysis of ATP and phospholipids, and also secondary messenger in metabolic regulation (Karthika et al, 2018). Like N, no significant difference was observed among the treatments (Table 3).…”

“…The highest speed of K release from plant residues can be attributed to the fact that K is an element that is not associated with any structural component of vegetal tissue, and found in ionic form with easily extracted from the plant tissue (Karthika et al, 2018) without necessarily having a biological decomposition and mineralization (Bernardes et al, 2010). Consequently, it is essential to reduce the implantation period of the successor culture to minimize the loss of K.…”

Plant cocktails used as cover crop present a significant multifunctional resource compared to monoculture, which may increase functional diversity within crop rotation and is particularly effective for designing mixtures with characteristics that increase the multifunctionality and sustainability of the agroecosystem. The objective was to evaluate sustainable agroecosystems models that improve the efficiency of nutrient cycling for crops. The treatments were arranged in four blocks in a split-plot design with two soil management (tillage and no-till) systems and three cropping systems (2 plant cocktails [PCs] and 1 natural vegetation [NV]). C/N ratio, lignin content, dry biomass (DB) production and decomposition, nutrients accumulation and mineralization by PCs and NV were evaluated. Decomposition and release of nutrients were monitored by the litterbag-method. PCs had a DB production twice higher than NV, essential for the adoption of no-tillage systems. The order of nutrient release was K> N> Ca> P> Mg. PCs as cover crops and green manure, with or without predominance of legumes and use of a no-tillage system, could be a technological strategy in agroecosystems for nutrients cycling in semi-arid regions.

“…The concentration of macronutrients required for plant optimal growth is above 0.1% on a dry matter in plant tissue (Karthika et al 2018). Therefore, as macronutrients are required at high concentrations, it is not common to find macronutrient toxicity stress in field conditions.…”

“…Nitrogen (N) is taken up either as the nitrate ion (NO 3 − ), the prevalent form of uptake, or as the ammonium ion (NH 4 + ), depending on the plant species and the soil conditions regarding factors like pH and the redox state (Karthika et al 2018). The principal transporters described for NO 3 − belong to the NRT family, a large protein family.…”

Interrelations of nutrient and water transporters in plants under abiotic stress

Environmental changes cause abiotic stress in plants, primarily through alterations in the uptake of the nutrients and water they require for their metabolism and growth and to maintain their cellular homeostasis. The plasma membranes of cells contain transporter proteins, encoded by their specific genes, responsible for the uptake of nutrients and water (aquaporins). However, their interregulation has rarely been taken into account. Therefore, in this review we identify how the plant genome responds to abiotic stresses such as nutrient deficiency, drought, salinity and low temperature, in relation to both nutrient transporters and aquaporins. Some general responses or regulation mechanisms can be observed under each abiotic stress such as the induction of plasma membrane transporter expression during macronutrient deficiency, the induction of tonoplast transporters and reduction of aquaporins during micronutrients deficiency. However, drought, salinity and low temperatures generally cause an increase in expression of nutrient transporters and aquaporins in tolerant plants. We propose that both types of transporters (nutrients and water) should be considered jointly in order to better understand plant tolerance of stresses.

“…These data must be interpreted with caution because there have not any research study highlighted before the nutritional value of P. quercetorum. Nevertheless, these differences between P. quercetorum and P. roseum can be mainly explained by the geographic origin, genetic, soil type, environment conditions among others which highly affected the nutritional values of the plant species (Clarkson 1985;Hornick, 1992;Karthika et al, 2018)…”

Pelargonium quercetorum Agnew is an edible wild species of Pelargonium genus which has a lot of concern in term of ethnobotanical knowledge, nutrition value and phytochemical analysis. Traditionally, it was providing local and rural people medicines and food security. Nowadays, wild edible plants (WEPs) become a central action to preserve the culture that belongs to the natural heritage. Thus, the aim of this research is to investigate ethnobotanical knowledge related to the traditions, phytochemical and nutritional value of P. quercetorum. Semi questionnaire has been used in Deralok town for ethnobotanical knowledge determination. The findings showed the main threats were overgrazing and overharvesting of this WEPs; a quantity of (10kg) took per year as a food and medicines during spring season. The plant was in a high abundance but required bio-conservation alongside it can be taken together with medication with the very rare side effect on the people. Furthermore, the analysis part has been done in the laboratories of college of agricultural engineering science, University of Duhok, Kurdistan region of Iraq. The findings of this research shown interestingly the highest level contents of (fat=3.68g / 100g, carbohydrate=46.78g /100g, dry matter moisture content=10.93g / 100g and fibers=20.56g / 100g), macro mineral (Ca=4512.9mg / 100g and Mg=229.69mg / 100 g), micro minerals (Zn=4.398mg / 100 g, Mn=3.926mg / 100 g and Cu=1.074mg / 100g) were seen in leaves part. But, the highest content of (Energy value 185.44g/100g, Protein 23.38g/100g and Ash 7.63g / 100g), macro mineral (P=928.5mg / 100g, S=4.036mg / 100g, K=1147.9mg/100g and Na= 118.54mg / 100g), micro minerals (Fe=23.779mg / 100g) were seen in root part. Hence, the study evidence shown that this geranium species can enhance nutrition value and food security as well as natural remedies for the local people
